Help Loking to get SAP-15 NO/PO Matched?

Well I am in a bind I have a DK Designs MK II amp that has a channel out it uses SANKEN SAP-15 NO and PO Series devices which I have found source for what I am unable to do is match the devices. I also would like suggestions on how best to restart and bias the amps once this is done. I am willing to pay someone to match the devices for me. Would anyone be interested in providing this service or know of a company that does. Thanks
